A Party at Napoli’s and Big Papi’s farewell are among today’s Topps Now baseball cards.

The lineup includes 18 cards available for only 24 hours via Topps’ online card program. David Ortiz‘s autographs along with Mike Napoli‘s marks the first time there are two autographs available on the same day — and they aren’t the only cards.

One of this year’s hidden gems on the field is nearly the same thing off of it — or at least on cardboard.

In an era of prospect cards made sometimes years before a player even sees an MLB field, Cincinnati Reds outfielder Adam Duvall is a bit of an enigma. Make that an enigma who has 18 home runs this season after a 9-8 victory over the Atlanta Braves Monday night where he led off the game with a two-run shot in the first.

The current SCP Auctions sale includes items from the personal collections of Baseball Hall of Famer Don Drysdale and collections of memorabilia that include plenty of other big names, but it’s a selection of championship rings here that’s highlight-worthy.

Below is a gallery of 18 rings up for sale now and ending on April 23. Click below to enter the gallery, get a closer look, see who’s owned them and what the bidding sits at now.

Topps‘ new program creating real baseball cards in real time documenting the highlights of the here and now have caught on with some collectors as this season has begun with some historic starts and impressive debuts for MLB rookies.

It’s 2016 Topps Now and the cards are only available for a 24-hour window. After that, the population reports are released and the next day’s cards are unveiled — all in made-to-order, real-time fashion.

There appears there could be a third version of Mike McCormick‘s card No. 86. When examining a group of 1967 cards, Buzz noticed a possible version (above) that’s not cataloged anywhere among the various error & variations lists or noted on any population reports despite this set being 49 years old. It’s a dramatically different version of the card for the Washington Senators pitcher who was traded to the San Francisco Giants, which is the reason for the variations to exist.

It turns out that this card is from the 1967 O-Pee-Chee set, though there is only one version cataloged there. Could a third version like this exist for the Topps card? Or are there two versions for O-Pee-Chee? Keep reading for the details.

The spring training drama that is Pablo Sandoval and his “waist management” concerns is the big non-story story so far, but there’s one statistic about the Boston Red Sox slugger that should matter to baseball card collectors.

The statistic is one — as in Sandoval is one of very few players in recent years to appear on just one Rookie Card. Yep, that’s it … one.
